If you're wondering whether this thing is worth it...the answer is yes. After 7+ years of daily top-offs and getting neighbors to come in when we're away, I finally decided to get the osmolator. Wish I had done it years ago. Works as advertised.
Accurate when it works By Ryan on 12/22/2012

I have had this since February of 2012 and have problems with it monthly if not a few times a month. When it doesn't stop working it keeps the level and salinity in my aquarium perfect. However, it continues to stop pumping water and the level will drop too much. I will then have to unplug the unit in order to reset it. I have contacted tunze about this and they have told me to check the contacts to make sure they are clean. They always are. Have yet to remedy the problem. If the unit would continue to operate constantly I would be giving the review 5 stars.
Neat By Ryan on 12/21/2012

Tunze osmolator is really easy to set up the only negative thing i can think of is when getting the pump started for the first time i had to give it a little shake to get it going. Very precise and i don't feel nervous leaving the house with it having a safety float switch. I drilled two holes in the side of a bucket towards the top to put the lines through and have a threaded lid on it that i got from lowes.
No more lugging top off water around By Nick on 12/7/2012

Very easy to set up. Only problem that I had was getting air bubbles out from bottom of pump upon first start. I put mine in a water storage container from a pet store instead of a bucket so I couldnt fit my hand in and turn the pump upside down to get the air out.... a little shake of the wires and bingo, that is my only gripe but other then that its very nice knowing that I can go days without having to fill a container for top off water
Dont know why I waited so long By UCFKnightFan on 12/4/2012

Great product after having to top off a gallon every day and worry about tuning my skimmer this product has been a no brainer. What caught my attention was the magnetic setup. I dont need to worry about suction cups or hang-on the side mounting. I used it in my baffled sump.
So much easier than daily topoffs! By Pat on 12/2/2012

I was really getting sick of adding water to my tank every day. This is the answer! Easy to install and so far works exactly as it should.

Nice ..... but beware of operator error, the tank sump cannot be lower than your reservoir or it will back siphon.

I finally set this up on my tank after waiting because I thought it was going to take too long. I was so happy to find out set-up took 5-10 minutes and now I have reliable redundancy on my tank.

Keeps water level stable along with salinity. One sensor and one backup float valve are included for peace of mind. Overflow sensor and alarm are a great addtion to my setup. Trusted unit!
Replaced my jbj auto top off By Thomas on 11/17/2012

I had some issues with my jbj auto top off unit and decided to try the osmolator. I can't believe the difference in quality! My only issue with this unit is that when the system comes back online it primes itself. If you are using kalk then it can add more to the system then the normal dosage

I have one of these units about 10yrs old. They havent changed much but havent had to as the unit just works. The new one comes with 2 magnet setups which back 10yrs ago when i bought my first one it didnt have. To put this in perspective I had to tweak this thing (clean/adjust) maybe 3 times in 10yrs. This is amazing. It just doesnt fail. Ordering 2 more right now.

My first one got fried in a lightning strike, it was super touchy! I was very frustrated with it, almost tried another ATO. The second one is bullet proof.
Why get any other? By Ben on 11/6/2012
Ben would recommend this product to a friend
I just purchased this, as my first ATO. I realize it is a little pricey, but in this hobby, you get what you pay for... I have been contemplating on what to get for months, after hearing from so many people that wish they would have went with this in the first place, I just decided to get it. I am glad I did. It is incredibly easy to set up, with little reading of the directions, I probably spent more time drilling through my stand than actually setting it up. it is pretty much a "plug and play" device, and it will come with everything you need. I ordered and picked up from BRS within a hour, as always the service I got once I was there was great.

Replacing the water evaporated form your tank is a chore and nightmare for every one in the hobby. so when it came for me to setup my 120 gallon tank this was one of the first piece of equipment i got for my reef. i must say simple to install and reliable it has never failed on me or flooded my basement. if you want simple reliable this is for you.

Bought this after getting fed up with making top off water everyday. A little pricey but it comes with everything you need and is easy to set up. The optical sensor is nice and was a selling point for me.

I have had saltwater aquariums for 20+ years. Iwork offshore and overseas.I have to depend on someone to check on my tank on a daily basis to add water. This Product was very easy to set-up. I tested it by turning off power, removing water and adding water, and it works great. This tank can go a week without supervision now...Probably the best piece of reef equipment i have ever bought.....Well worth the price!!!!
Best ATO By Chris on 10/13/2012

Seems like lots of money compared to some of the other ATO but it's worth it. Nice to have something that is reliable and gives great piece of mind that it's just going to work.

I've had mine for over 1yr. It's never given me the slightest hiccup.
I use a small reservoir for top off water (2.5g jug). My jug has run out of water on a number of occasions. The pump included in this unit is very durable. I think most other pumps would of been smoked by now.
Works Great as an RO/DI ONLY Top Off By Toby on 9/20/2012

Works great as an RO/DI ONLY top off but I would not trust it to top off with KALK. The optical sensor works great! This product will help you enjoy the hobby.

This is one of the best aquarium devices. Just add water to the top off container once a week and forget about it. Easy to set up and the magnet holders work great.
